You've officially reached the mainstream when you've attained this level of parody.
Don't get me wrong, I love the fixie scene and embrace subculture with open arms- as somebody who spent a large part of my life in subcultures of various types, I will always have a love for it.
BUT... you have simply got to admit that this video is superbly done and funnier than all heck. (Be warned, the language is more R than PG... so send the kids to go get you a cup of coffee...)
Thanks to Fritz for the info. I have to imagine that the BSNYC is all over this already... but I haven't seen it on his site yet.
